Maltysen

oh lol

what was the other one?

orlp

@Maltysen my personal malware muhahaha

nah

ninja package in Ubuntu
ninja: Privilege escalation detection system for GNU/Linux

not sure, never used it

Maltysen

well it couldn't find it in my regular user, ran it as root and it failed

oh right

cd ..

rm -rf kwik

git clone --recursive https://github.com/orlp/kwik

forgot that git doesn't clone subrepositories by default

Maltysen

No submodule mapping found in .gitmodules for path 'src/libop'

hrm

allright, I believe my git repo is broken then

give me a few

Anonymous

@quartata Smartass correct answer :P I've also offered an unending bounty on it for a smart answer

orlp

@Maltysen ok, remove and clone recursive again

or try git pull && git submodule update --init --recursive

Maltysen

k it worked

orlp

it built?

Maltysen

no it clones, its building right now

orlp

6:11 AM

ah

Maltysen

g++ --version?

I believe I require too modern g++ then, but I think I can implement this in a less modern way

I tried compiling it under 4.9.3, got an error that _assert wasn't defined

@Mego full error msg?

Linux hates me

I'm root and I get a "Permission denied" error!

orlp

@Mego this is a bit harder to solve

@Maltysen try pulling and building

hrm

you did pull?

did it say it got anything?

maybe you also needed to execute git submodule update --init --recursive?

Anonymous

I did git pull --all and got the latest

6:22 AM

Probably easier than that :P

Maltysen

it gave me +1 and -1

Q: Count the divisors of a number

Introduction This is a very simple challenge: simply count the divisors of a number. We've had a similar but more complicated challenge before, but I'm intending this one to be entry-level. The Challenge Create a program or function that, given one strictly positive integer N, outputs or retur...

orlp

because I just fixed that error maltysen

if git pull --all doesn't work neither git submodule update --init --recursive then I guess just rm -rf kwik and clone recursive again

I should really learn how submodules work someday

orlp

allright, I messed up

should work now, for both of you @Maltysen @Mego

(after pulling of course)

(and assuming there aren't further issues)

Maltysen

6:33 AM

yay it worked

yep

Anonymous

@orlp same problem

Anonymous

nvm did submodule update and it's good

orlp

@Mego rm -rf kwik and clone recursive

ah

Maltysen

wow 7 answers in 17 mins

what does this thang do

I like how I'm tying with Mathematica... :P

A: Count the divisors of a number

Seriously, 17 bytes ,;n;;╟@RZ`i@%Y`MΣ Try it online with explanation If my prime factorization function had been working before this challenge, I could get 9 bytes: ,w`iXu`Mπ

orlp

seriously?

It's always sad to discover interpreter bugs while doing a challenge

orlp

@Mego get a better testsuite

Question about Golfscript

El'endia Starman

6:53 AM

I should probably make a test suite for Minkolang.

Sherlock9

If I have a stack r [a..b] {*something*}* where r,a and b are numbers and I want what's in the block to change r by using the stuff in [a..b], how do I do that?

orlp

haha

Pyth5's testsuite is already over 1300 lines long

and not many of the operators are implemented

Sherlock9

Do I + r into the block? And what does that do exactly?

orlp

@Sherlock9 the answer is use pyth

Sherlock9

I'm already learning one language in under a week, let's not throw another one on there yet, @orlp

... @orlp After skimming the docs, I may stand corrected. We shall see.

feersum

6:58 AM

Deciding to learn Golfscript now is like deciding to learn COBOL.

orlp

Duplicate of codegolf.stackexchange.com/questions/48406/…? — orlp 13 secs ago

Sherlock9

@feersum Depends. Are you working with NASA computers? They need FORTRAN programmers

feersum

I said COBOL, not FORTRAN.

orlp

why are we SCREAMING

Sherlock9

@feersum Well, FORTRAN definitely, COBOL maybe at NASA, but I don't remember exactly

Because programming languages were named with the Caps Lock button on

In the early days

*CAPS LOCK

Say, @orlp, at the time you were busy, so I'll bring this up again.

1 hour ago, by El'endia Starman

@orlp (sqrt (* 2 8)) ⇒ 4.0 <- I don't get this. Why does this work? Is sqrt already a built-in function?

orlp

my bad

got distracted

El'endia Starman

totally understandable

orlp

@El'endiaStarman you are on the page of lis.py right?

ctrl+f for env.update(vars(math))

El'endia Starman

yup

ahhh

So basically, it was imported.

orlp

yes

El'endia Starman

7:05 AM

Another question: does "anything" also mean other expressions?

> If proc is anything other than one of the symbols if, define, or quote then it is treated as a procedure.

orlp

@El'endiaStarman correct

((quote sin) 3.5)

El'endia Starman

gotcha

orlp

I think lis.py is a double-win

it introduces people to how compilers work

and the elegance of lisp

@Optimizer Are you calling Alex fat?

Optimizer

wow, how do you infer that from the above line?

Anonymous

You totally are calling Alex fat! That is a valid and rational assumption from your statement!

Alright that's too far

Optimizer

seriously dude? you yourself start this and the second i join your jokes, you flag it?

orlp

relax guys

Optimizer

7:29 AM

@Mego if you can't take a joke, don't do it on others.

Anonymous

@Optimizer I responded with obvious sarcasm. You directly insulted me.

Anonymous

> That is a valid and rational assumption from your statement!

Optimizer

@Mego I don't see how that was obvious.

Also, you are a penguin. so that counts as a valid and rational extrapolation from your valid and rational assumption

from now on, I am simply gonna ignore anything you say in order to prevent myself from getting uselessly chat banned.

Anonymous

That's a mature response

Anonymous

This is stupid

Sherlock9

7:34 AM

Pyth is giving me headaches

/me continues to read docs

Optimizer

don't worry, its supposed to do that initially

orlp

@Maltysen btw my compiler so far is only parser/lexer

of a small subset

just been doing all the infrastructure work

I'm going to kill my ISP. The last 30 days had over 57 hours downtime.

I can't even contact support because their web-server and landline crashed!

Sherlock9

@Optimizer How does array[n] in Pyth?

orlp

@Sherlock9 @_n

where _ is your expression with the array

Sherlock9

Thanks

feersum

In Pyth5 @ <recipient>< message> sends an email.

orlp

lol

Sherlock9

8:17 AM

Ok so I tried to do a sum of divisors thing by multiplying the head(exponents) of the prime factors

J{PQK1FNJ=*Kh/PQ@JN;K this is my result

Is it just me, or is this a tad verbose for Pyth?

orlp

I did it in 10

although it was broken for input 1 and 0 (n>=2)

hint rPQ8

also, check out m

you almost never use F for for loops

also check out *F

Sherlock9

Thanks
